Rtl8822cs sdio board on M5

syntax error near unexpected token `then’

Not sure, but is your bash shell available? And the build is done through docker right?

I am not using docker, I build on Ubuntu 22.10 and I expect Bash is available. The only strange thing is that the build process request root password !

I migrate my PC to Ubuntu 23.04 and the build process terminated fine. The patch seems integrated well during build.

Now I will try to boot the board with this build.

I will let you know the next step.

@boyi Thanks the board boot this build , it works on EMMC and the device wlan0 is there. Now I will configure and check that the device driver is stable. Gerard

@gege_fr My pleasure. That’s really good to know.

Regards.

I try to move my M5 board and its rtl8822cd board (sdio) to bookworm 24.2 build. After some research I discover that the sdio board has been integrate in the build and after adding

overlay_prefix=meson-sm1-bananapi-m5 overlays=rtl8822cs

to /boot/armbianEnv.txt and 88x2cs to /etc/modules

the interface seems recognized by Linux

As i can’t start the AP mode I try in client mode and the board works and connects a SSID.

After further investigations and comparaisons with 22. release, I saw the /lib/crda directory was missing in 24.2 distro and I copy it from 22.

dispit all my research I am blocked and can’t start hostapd.

I try the manual start of hostapdand got an error 47
